Show full process name in top

Question

I'm running a rails stack on ubuntu.

When I ps -AF, I get a descriptive process name set by the apache module like

00:00:43 Rails: /var/www...

which is really helpful in diagnosing load issues.

But when I top, the same process show up simply as

ruby

Is there any way to get the ps -AF process name in top?

Answer 1

While top is running, you can press c to toggle between showing the process name and the command line. To remember the toggle state for next time, press W to save the current configuration to ~/.toprc.

Answer 2

When running top type c to toggle command line/process.

Answer 3

This is more of a general suggestion, than an answer:

Try out htop. It shows the full process name by default and I think it's much easier to use.
